Reservoir Characterization & Geological Modeling (QCB4043)

These flashcards cover key terminology and concepts related to reservoir characterization and geological modeling as per the lecture notes.

Well Log Correlation

Detailed information at the borehole which correlates stratigraphic units based on well log responses.

Lithostratigraphy

Correlation based on lithologic units, often used in well log correlation.

Chronostratigraphy

Correlation based on time-equivalent stratal packages or parasequences.

Datum

A reference horizon used to correlate well logs to a common depth.

Subsurface Mapping

Representing a 3D surface on a map to illustrate geological features below the surface.

Seismic Data

Information gathered from seismic waves that is critical in reservoir modeling.

Porosity/Velocity Transform

A method of converting data to depth in geoscience.

Contour Map

A map where contour lines separate points of different elevations.

Isopach Map

A map showing lines of equal thickness of strata between two planes.

Fault Modeling

The process of visualizing and representing fault lines and their effects on surrounding geological structures.
